It is not just comets- all orbiting bodies speed up as they get closer to the object they are orbiting, as stated by Kepler's Second Law, because the gravity between the two objects gets stronger as they get closer together, as stated by Newton's Law of Universal Gravitation.
What else can I help you with?
Why do you think that the speeds of comets increase as they get near the sun?
Comet speeds increase as they near the sun due to the sun's gravitational pull. The sun's gravity accelerates the comet as it moves closer, causing an increase in speed. Additionally, as the comet nears the sun, it is subjected to increasing solar radiation and solar wind pressure, which can also contribute to its acceleration.
Will a planet or comet be moving faster in it's orbit when it is farther from or closer to the sun?
A planet or comet will move faster in its orbit when it is closer to the sun due to the increase in gravitational pull. As it moves farther from the sun, its speed decreases as the gravitational force weakens.
Do comets appear darker or lighter as they get closer to the sun?
Comets get brighter the closer they get to the sun for two reasons: the sunlight is brighter closer to the sun than it is further away and the comet heats up closer to the sun causing outgassing and the formation of a large coma composed of dust particles and gas around the comet itself giving a much larger area for sunlight to reflect off of.
Why planets orbit the sun in different speeds?
Planets orbit the sun at different speeds because they are at varying distances from the sun. According to Kepler's laws of planetary motion, planets closer to the sun have faster orbital speeds, while those farther away have slower speeds. This is due to the gravitational force exerted by the sun, which is stronger on planets closer to it.
Comets are invisible except when they are near what?
Comets become visible when they are closer to the sun and begin to heat up, causing them to develop a visible coma and tail. This closer proximity to the sun typically occurs in the inner solar system, where they become brighter and more conspicuous.

Why do you think that the speeds of comets increase as they near the sun?
It gives off gas and dust in the form of a coma and a tail.
Why the tail of comets increase or deacrese as it goes round the sun?
The tail of the comets is caused by the solar wind - particles blown away form the Sun. When the comet is closer to the Sun, the solar wind becomes stronger.
Will a planet or comet be moving faster in its orbit when it is closer to or farther from the sun?
Planets and comets move faster when they are closer to the sun.
Will a planet or comet be moving faster in it orbit when it is farther from or closer to the sun?
Planets and comets move faster when they are closer to the sun.
What member of the solar system has a highly eccentric orbit?
Comets. They spend a lot of their time moving slowly at far distances from the sun, with brief periods of time spent closer to the sun, moving at higher speeds.
Will a planet or comet be moving faster in it's orbit when it is farther from or closer to the sun?
A planet or comet will move faster in its orbit when it is closer to the sun due to the increase in gravitational pull. As it moves farther from the sun, its speed decreases as the gravitational force weakens.
What are some What are facts about comets?
As a comet gets closer to the sun its speed increases.

What body has the fastest orbital speed as it orbits the sun asteroid or comet?
Comet. Comets typically have faster orbital speeds than asteroids as they move along highly elliptical orbits that bring them close to the sun, increasing their speed. This is due to the gravitational pull of the sun that speeds up comets as they approach perihelion, their closest point to the sun.
